  • Protection of a communication line
    Patent number: 7746618
    Abstract: A circuit for protecting electronic equipment intended to be connected to at least one first conductor of a communication line, including, between this first conductor and a second conductor of the line or the ground to which is connected the equipment to be protected, at least one first branch including, in series, a first capacitive element and a first voltage-threshold triggering element, a first resistive element being connected in parallel with the first capacitive element.
    Type: Grant

    Assignee: STMicroelectronics S.A.
    Inventors: André Bremond, Cédric Appere
  • High-frequency coupler
    Patent number: 7005941
    Abstract: A high-frequency coupler for extracting a secondary signal representative of a main signal carried by a conductive line, including two series-coupled, respectively high-pass and low-pass, filters, and the input of which is intended to be connected to said line while its output is intended to provide the secondary signal, the filters being sized so that the sum of their respective attenuations is substantially constant over the coupler passband, and so that their respective cut-off frequencies are in said passband.

  • Circuit for protection against heating of a protection element of equipment
    Patent number: 6850400
    Abstract: A series device for protection against a heating of aparallel protection element of an equipment of a telephone line, including a bi-directional cut-off element, of normally on state and placed in series with the parallel protection element, a temperature detection element, and a switching element adapted to turning off the cut-off element when the temperature detected by the detection element exceeds a predetermined threshold.
